SAWP.HIVE is another cryptocurrency. In Splinterlands it gets used when you send Splinterlands currencies to Hive-Engine and you want to convert them to other Hive currencies, or you want to Power Up your Hive account for more voting power and to be able to do more transactions on the Hive Blockchain (where Splinterlands operates on). There are several ways to exchange SWAP.Hive crypto into Hive crypto. You can do this in your hive wallet or in Hive Keychain, but it can also be done in BeeSwap:
Step 1: Go to "https://beeswap.dcity.io/convert"
Step 2: Click the login button, and sign into the website just like you would do so with your Hive keys in Splinterlands. (In this example we use Hive Keychain, so if you use a different way to verify your keys it may look different).
Step 3: Enter your amount of SWAP.HIVE to swap for HIVE, OR click on the arrows in the middle of the page to swap HIVE for SWAP.HIVE.
Step 4: Confirm the transaction with your key in order to proceed with the transaction, and therefore completing the swap.
